Export

Geojson is a good format for the data. It is flexible and allows you to add your own data to the structure. It’s quite easy to read, but it can be inefficient with large data sets and polygons (consider Topojson if project can work with modern browsers <IE8)

To export:

Tools -> Script Editor

“Create new project”

“Blank Project”

Paste in this script -https://raw.githubusercontent.com/mapbox/geo-googledocs/master/MapBox.js

Publish->Deploy as Web App

Spreadsheet -> select rows -> Geo -> Export

Display

Try using http://geojson.io

Cut and paste the geojson data exported above into the text window.

Your points will appear on the map

Table view is good to see and scan your data

Use Github pages – free hosting and version control. Update the data using http://geojson.io
